Some later model wireless routers have the Password(ie.Encryption key) and the SSID already configured in the wireless router andthis information is printed on a label on the bottom of the router.These settings can be used to configure the wireless card and wireless adaptersin your computer/laptop. If these settings do not suit you, then it can be changed to suit yourrequirements. The encryption key secures your data and wireless connection from unauthorizedaccess.To configure the wireless settings in the router, connect a LAN cablefrom your computer to the wireless router, then open a Browser on your computerand enter the router's configuration IP address, then enter the admin login andpassword and then go to the wireless settings and configure the SSID andEncryption key.The router's encryption key can be a Passphrase or the WEP or WPA or WPA2key.If you use the Passphrase method select either WEP or WPA or WPA2 togenerate the encryption key. You can enter the WEP or WPA or WPA2 key with 8 to63 ASCII characters or 64 Hex digits.Most people use Passphrase which is easier to remember eg. I was born inJanuary 1988.The strongest and latest security is WPA2, the weakest and oldest is WEP. Toconnect to your wireless router from the computer/laptop, configure thewireless card in your computer/laptop with the router's wireless settings ieSSID, plus the WPA or WPA2 encryption key. Then computer/laptops cancommunicate with your wireless router.http://www.fixya.com/support/r10267861-network_security_key

Try RESETTING the Netgear back to the default setting and then configure it again.
To RESET the Netgear, power up the Netgear then press andhold the RESET button at the back of the router until all the LEDs flash.
Connect a LAN cable from the Netgear to the LAN port on yourcomputer, open a browser and enter the Netgear configuration URL -http://192.168.0.1The default login = adminThe default PW = password
You can now change the admin password and configure thewireless settings.Go to the wireless configuration and set up the SSID and WPA or WPA2encryption.Apply these settings to the wireless card in your laptop/computer.

If this does not work then the Netgear routy is faulty, then you need a new wireless router.

1-In order to get your router back to the original settings, you must push
in the reset button (usually on the back of the router) for somewhere
between 10 and 30 seconds depending on the router. You may need a pin or
something small to push in the button, because it can be recessed. Once
you have reset the router, the username and password will be changed to
the defaults, admin and password, respectively. One thing you must
remember is that resetting the router will change all of the router
settings back to the factory settings. This means you will lose all of
the changes you made since you got the router. Make sure to write down
any things you've changed, so you can change them back after the reset.
Also, I recommend updating to the latest firmware after the reset.
